NAME
Carp::Source - Warn of errors with stack backtrace and source context
VERSION
version 1.101420
SYNOPSIS
use Carp::Source 'source_cluck';
source_cluck 'some error';
source_cluck 'some error',
lines => 5, number => 0, color => 'yellow on_blue';
DESCRIPTION
This module exports one function, "source_cluck()", which prints stack
traces with source code extracts to make it obvious what has been called
from where.
It does not work for one-liners because there is no file from which to
load source code.
FUNCTIONS
source_cluck
source_cluck 'some error';
source_cluck 'some error',
lines => 5, number => 0, color => 'yellow on_blue';
Like Carp's "cluck()", but it also displays the source code context of
all call frames, with three lines before and after each call being
shown, and the call being highlighted.
It takes as arguments a string (the error message) and a hash of
options. The following options are recognized:
"lines"
Number of lines to display before and after the line reported in the
stack trace. Defaults to 3.
"number"
Boolean value to indicate whether line numbers should be printed at
the beginning of the context source code lines. Defaults to yes.
"color"
The color in which to print the source code line reported in the
stack trace. It has to be a string that Term::ANSIColor understands.
Defaults to "black on_yellow".
This is just a quick hack - not all of "Carp"'s or even just "cluck()"'s
features are present. The code borrows heavily from "Carp".
